To (til whom it may concern.-

Be it known that I, Joan N. LnAoH, a citizen of the United States,residing at .Melrose, in the county of Middlesex and State of ltlassa 5chusetts, have invented certain new and useful improvements in Apparatusfor Generating and Burning Gases from. Hydrocarbons, of which thefollowing is a specification, reference being had therein to theaccompanying I0 drawings, which form a part thereof.

My invention relates to an apparatus for generating and burning gasesfrom hydrocarbons, and more particularly to a class of burn crsespecially adapted for heating purposes and to use kerosene, crude oil,or other hyd rocarbons.

The object of my invention is to provide an apparatus for generating andburning from hydrocarbons. wherein the kerosene or other oil will beeffectively volatilized and mixed with oxygen before its introductionwithin the combustion-chainber.

A further object is to provide an apparatus 3 of. this class wherein theflame maybe readily controlled -that is, capable of being reduced orextinguished, increased, or relighted at any time-and wherein thevolatilixation of the fuel-oil when interrupted may be resumed withoutthe necessity of manual ignition to start such renewed volatilization.

A still further object is to provide an apparatus of this class whichwill be automatically lighted and rclighted.

A still further object is to provide an apparates of this class whereinthe vaporizing of the oil will not be dependent upon boiler heat underany conditions. i

'A still further object is to provide an apparatus of this class whereinthe dangers of back tiring f om the combustion to the mixing chamberwill be reduced to a minimum, il' not entirel obviated; and astillfurther object is to provide an apparatus of this class wherein thesupply fuel may be used under andalso 'apable of convenient regulation.

The invention consietsin comblnmg-with a burner a vaporizer comprising avaporizinghigh pressure to force the flame when desired lcoil and asuperheatine-eoil formed oil a con tinnous pipe wherein the :lueboil issubjected 5 to successive lie-noes, whereby the oil is vapo rized andthe vapor inperheated before being thoroug'i'ily ruined with oxygen andintro duccd within tllib(10m JliiFtlitift-lill.l1filifll. f it furtherconsiete in the utilization of an auxiliary burner having a permanentflame the com bustiodchamher of which is either a part of or in directcommunication with the combustion-chamber of the heatii'ig--l)ui'ner;and it consists, still further, in these novel few tures' ofconstruction and arraugmnent of v parts hereinafter set forth duddescribed. and

more particularly pointed out inthe claims hereto appended.

Li he letters refer tolilce parts throughout the several views.

- In Figs. 1 to 3 of the drawings l have shown the apparatus as used inconnectiouwith the boiler ot'a steam-carriage and in Figs. 45 to 10,inclusive, as used in connection with a Fig. 7 is a horizontal secplicable only to such; uses-J} 1 My burner comprises anlinclosingcasing,

as a, which 'is divided into separate mixing chambers d and e, eachprov'ided with an individual burner-plate, as-b and c, andinto acombustion-chamberf, extending over and common to both burners." Forconvenience burner 0 will hereinafter be designated the primary burnerand bhrner b the secondary? burner. A top plate or plates, as g,'Figs. 4to 6, and 8; Fig. 1, are provided for the en- 'tire combustion-chamberf. To prevent-interleren'ce between the' secondary burner and the flameof the primary burner, Iso divide the combustion-chamber f. adjacent tothe' qrilatter-as 'tbhave the different portions of said'combustiomchamber communication only at a 'point some distance abovethe burner c and provide an.ir nperforate top plate 7 or a; hood, as g,Figs. 4 and 5, directly abovethe primary burner to confine the flame,thus preventing the extinguishment of;'.th.e flame of this burnerfromback draft due'to'the igni-- tlon of'thesecondary burner therefrom.

The oil, whether kerosene, crude oil, or other hydrocarbon i used, isstored in a det'ached tank (not shown) and is fed to ,the

secondary burner through a pipe t, which is passed into thecombustion-chamber f and formed into a vaporizing-coil 7," directlyabove "the secondary burner b, thence through said,

chamber to directly above the primary burner -0, where a second suchcoil, constitutinga superheating-coll 2", IS formed, of a size to bestexpose all parts thereof to the action of the primary flame or torch,and. thence tothe' a mlxlng-chamber (Z, where it terminates in aspraying-nozzle 2' controlledby a needle point valve 71. It willvaporizer, comprising'tie vaporizing-coil v1 and superheatiug-coil a"and the portions of pipe connectingthese coils',all-contained within thecombustion-chamber f, feeds the ,secondary burner I) only.

A separate system of piping, as k, which may take its oil from the sametank as pipe 27 or from a separate tank, feeds the primary burner c;.Thispiping Z; is passed vertically through the mixing-chamber c and thecoil 9: I

Ithiiis been found, however, that in burners emlo'ying thin or 'sheet-metal burnerfplatesth e danger from back firingfromfithe combustion to the mixing cham her is great when said platesbecome over-heated or reach a red heat. This danger is obviated byproviding the burner b with a facing of-asbestosor other materialnon-conductive of heat, as b", on either the top or the .bottom thereof,or both, in the spaces between the slots 6' and the separate tiersof'said slots; This has been found to practicaiiy eliminate this dangerof back firingfrom this source, no conditions having developed whereinsuch takes place.

The form of burnershown has proved effective in 'use; but otherforms can be used, if desired.

Adjacent to the burner 01 provide a needle;

The construction-and arrangement heretofore described are common to allforms of my invention, and thediiferent applications thereof entailmerely immaterial variations in the relation of these parts and otherdetails of construction necessary to their use in a definite connection.

In Figs. 1 to 3, inclusive, 1 have shown the apparatus as applied to asteam carriage primary burner 0, its mixing-chamber c, and its portionofthe combustion-chamber f are arranged at one side of the secondaryburner boiler. This is preferable, as by such arrangement the secondaryburner constitutes the sole source of heat for generating steam,- andthe permanent flame of theprimary Preferably the primary burner c is ofthin point valve is, the stem is of which passes in using my apparatusthe oil may be fed \Vhatever the system boiler, as above stated.

The apparatus issuspended within the base of theturmiee, as the ordinary fire pot', bymeansot' the flange a. and an additional support therefor is provided.as the standard it, within the ordinary ash-pit To prevent as much aspossible the radiation; of heat, the casing (i above the burner 11 am Idie protected by a sheathing of asbestos, 1 tire-brick, or other similarmaterial Hi. The l pit p" constitutes a tresh-air chamber with which themixing-tube and the air-inlet 1 I of the mixing-t11be are incommunication j and drawtheir supply of air. For con\'en 1 ience in thistype ol apparatus the primary burnerw: is arranged within the secondary3 l'iurner/Jinstead ol at one side thereof, and the 5 mixing-chamber Iand hnrnenplate w are arranged belowthe level ol the secondary burnerI), thus dispensing with the partition liot'l igs. I 1 and 2, yetprotecting the flame of this burner from the eil'ects of back draft. Thehood 1/,

' arranged above the burner r. serves to conline the l'laine of thisburner and aids'in so protecting it. The top plate in this form ofburner is provided with a plurality of small openings, which enablesthis plate to 5 act as a deflector to conline the flame of thesecondaryburner more or less within the combustion-cllamher to. insuremorepertect E combustion and avoid contamination of the air within thechamber i by the unconsunied gases and to deflect the vapor into thatpart i 1 any desired lorm.

The apparatus is here placed beneath l,

of the coinbustioirchamber over the primary burner, so as to insureignition.

'lhe corrugations ol' the burner I may take In l igsQl to inclusive,they are shown in a plurality of parallel ceneentric circles and inFigs. ti and 7 in straight parallel lines. i

The operation ol the heretolbre-described apparatus whatever itsapplicatioi'l, is in so far as I have been able to determine as follows:lo Ignite the apparatus, a small amount of alcohol is placed in the pan'and ignited and the lmmlle-point valve A" opened after the vaiorizerportion hasbeen suflieiel'itly heat- 1 ed, the sullicienev olheat being ascertained by the color of the llameandthe perfection ofprimary burner. and it is iinperforate to the eomlmstion in the primaryburner. As

1 the oil passes through the portion of thepipe A adjacent to said panthe heat and flame therelrmn and the alreiuly-heated pipe vaporize it,and in this state it is charged jntothe mixing-tube where it receives aneffective :uhnixture of oxygen through the air-inlet 'lhrough the tubeit passes to tllGHllX- lug-chamber w and from there to-thecombustion-chamberf1 through the openings 1: c in the primary burner 11,where it becomes ignited from the flame of thenlcohoh The 1 quantity ofthe alcohol being small, its flame f soon dies klown, so that. thevolatlhzatlon of the oil passing through pipe Z' is continued solely bymeans of the flame from the primary burner r, the flame of which fromthis source is thus rendered self-sustaining and permanen t. \Vhen it isdesired to light the second- I ary burner, the i'leedle-point valve 11isopened to permit the passage of oil to the vaporizer through pipe I.This initial charge by con- [act with the superheating-eoil f fl whichis kept hot by the flame from the primary burner w, iscom'erted into avapor more or less super heated, which passes through the nozzle 1' andmixing-tube j, where it receives an admixture of oxygen, to the mixing=chamb w (I. From this chamber it passes through theslots b b in thesecondanv burner/; to the combustion-chamber f. The accumulationof thisvapor or gas in the eoml1ustion-chamberfl it is ammrent, is self-ignitedfrom the primary burner r. The flame thus produced is atlirst ablue-vapor llameol apparent good combusr tion, but alter thevaporizing-coil becomes a dull cherry-red color changes into a nearlytransparentflameof moreperfectcombustion. This flame acts directly uponthe vaporizingcoil f and thereafter vaporizes theoil at this point suchvapor being afterward passed through the sn1im'lfieating-coil 1", whereit is through the mixing-tube j to the secondary burner 11. The fuel-oilis therefore subjected while in the vaporizer to the continuous heat andsi'iceessivcly to the flames of said secondary and said pri mary burner."hen so. passed 4o fuel-supply-pipe systems.

that the fire can be forced to any desired ex-' furnace and described,

" through the two coils, asabove stated, a pure hydrocarbon gas isgenerated, which when. mixed with oxygen, the admixture of which isregulated by means of the needle-point valve i, develops an intense heatwith a small expenditure of liquid fuel. With the ignition of thesecondary burner b from the primary burner c a back draft is created,which tends to extinguish the flame of the latter. The partition It inthe form shown in Figs. 1 to 3 and the arrangement of the ,burner c on alower level than the secondary burner l), as shown in Figs. 4 to 7,inclusive, thus having the point of communication between the portion ofthe combustion-chamber. adjacent to said primary burner some distanceabove said burner and the imperforate plate or hood to confine itsflame, serves to protect this flame from the effects of this back draft.

\ l' zo The intense heat 1n the combustion-chamber f has heretofore beenfound to overheat the burner-plates when thin metal was used for thesame to an extent which induced back firing tothe mixing-chamber, withits resulting 2 inconvenience and injury. The non-conductive facing bhas been found to quiteeflectually prevent this overheating and theresults therefrcim.

The volume of flame is controlled by means 59 of the valve 11 and maytherefore be readily regulated from any convenient point where thisvalve'is located. If it be desired to extinguish the flame entirely,this may be done by means of this valve, and the burner b may berelighted and the flame again produced to the desired extent by simplyopening this valve, as the closing of the valve does not af-- feet theprimary-burner flame in anyway, these burners being supplied fromseparate It has been found tent without adversely affecting combustionor injuring the burner in any way.

The application of my burner to a heatingresults in the production of anefiicient, clean, and economical means of heating and such as can bereadily regulated.

It is not my intention to limit the invention to the details ofconstruction as herein shown as it is apparent that the burner may bevaried without departing from the spirit and scope of my invention.
